The use of Remote Reset
In case the ACB operates due to accidents or over current, the OCR indicates the information of the accident
through the LCD and LED. To operate it for the next accident, the P and S type have to be Reset.
1) Methods to Reset the P and S type are to push the Reset button and to Reset by short-circuiting Remote
Reset. Therefore, the Remote Reset does the same action as the Reset Key on the frontal side of the OCR.
2) Short-circuiting terminals R11-R22 resets.
3) R11-R22 are Dry Contacts that hold 3.3V of recognition voltage. When short-circuiting with SSR (Solid State
Relay) or Open-Collector, connect Collector (Drain) to R11.
4) For general Solid Relays, attach contacts disregarding directions.
